IMPROVEMENT IN WIRE-GUIDES FOR PAPRi'IVlACHINE'S.

Specification forming part of Letters'Patcnt N o. 212,485,

dated February 18, 1879; application iiled December 7, 1878.

To all whom it may concern:

Be it known that I, JOHN W. MOORE, of Wilmington, in the county of New Castle and State of Delaware, have inyented certain new and useful Improvements 1n Vire-Guides for Paper-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. ,f/

This invention relates to that class of machines which is designed for the purpose of keeping the wire-cloth in a paper-machine in its proper position laterally; and as the wirecloth will move laterally to one side or the other, this apparatus is designed so that the leastpossiblemovementwillbeatonce checked, which desired result is obtained by simply moving one end of the wire-cloth roller. This causes the wire-cloth to take the desired direction and position on it, all of which is more fully described hereinafter, and by the aid of the drawings, in which- Figure l is a front elevation. Fig. 2 is a plan. Fig. 3 is a side section of the slide.

In all the gures the same parts are referred to by the same letter; and to enable those skilled in the art to make and use my invention, I will proceed to describe the construction and operation thereof.

The bed-plate A, which is to be secured to the frame of the paper-machine or other suitable place, is provided with two smooth faces, al and ai", on or to which belong two projections. These projections are to t into and project upward into corresponding grooves in the faces formed in the slide B. Said slide is to move on the said faces al and a2. The slide B is held in its position on the bed-plate A by means of the screw-bolt D. This is accomthe slide B, they having a hole through them, through which said bolt D passes, and, in connection with a screw-nut ratchet-wheel, O, placed between said ears b1 and b2, holds the slide B in position so as to allow it to slide laterally in either direction by the action of revolving the said screw-mit ratchet-wheel O. The bolt D i.:

- ble crank F.

securely fastened to the sides a3 and a4 of the bed-plate A 5 and the arrangement of the slide B is so that the screw-nut ratchet-wheel O is to the back enveloped in a covering formed by the extension of the ears bl and b2 and connection of slide with its lower face, for the bedplate A, which is clearly shown by Fig. 3. On

the top of the slide B is a hole, to receive the pivot-bolt ofthe bearing B', in which the journal of the roller E rests, this pivot compensating for the slide action of the slide B. At the outer end of the journal E is the adjusta- This is held in position by a bolt, f, the tightening of which serves to adjust said crank. On the crank-pin f is placed the eye of the double pawl Gr. Said pawl eX- tends downward, and branches out into the double pawls gl and g2. They are made to pass to either side of the screw-nut ratchetwheel O, and the end g1 engages the ratchet O when descending, and the end g2 engages the same when ascending, said motion or action being derived from the crank F of the roller E, and the distance between the two ends of the pawls g* and g2 is so adjusted as to just clear the ratchet-wheel O. To the side of the pawl g2 is the eyelet g3. This is connected with a rod, H, and said rod again connects with the double right-angle action I, the lower connection, t", engaging the rod H, and the upper connecting-lever, i2, with the side guides, between which the ilat wire cloth runs or moves. This action I is supported on the end of a projection, a5, belongingto the bed-plate A, and on which projection is a pintle, as. This permits the action l to be pivoted thereon.

The operation of the invention is simply that, as the roller E revolves, the up-and-down motion is imparted through the medium of the journal to the crank, to the double pawl, and at a speed equal to its revolution, one thrust down and one up, to the turn of the roller; and should the lever of I be pressed in the slightest degree the rod H would draw the pawls g1 and g2, or push the same, thereby cans ing them to at once come in contact with ei- "ther side, as the case may be, of the screw-nut ratchet-wheel O, and, giving it a turn, would slide the slide B, therewith checking or at once guiding the wire-cloth, so as to cause it to cease acting on the lever of I.

Having thus described the construction and Operation of my invention, what I desire to secure by Letters Patent of the United States is as follows:

1. In a construction for guiding Wire-cloths or belts, the crank action, substantially as described, for operating a double pawl, to engage by draft or thrust a screw-nut ratchet- Wheel, to slide laterally a slide or purchase, substantially for the purpose set forth.

2. The combination, With the journal E of a roller, E, of an adjustable crank, F, to operate double-acting pawls G, to operate in either direction a ratchet-Wheel, substantially as herein set forth.

3. The combination of a bed-plate, A, and fixed screwbolt D, with a screw-nut ratchet- Wheel, to hold and operate a slide, B, by the action of double pawls operated by a crank, F, substantially for the purpose set forth.

In testimony that I claim the foregoing as my own I ax my signature in presence of two Witnesses.

JOHN W. MOORE.
